Perhaps we should see the first attempt at this uprooting of Anthropology - to which, no doubt, contemporary thought is dedicated -in the Nietzschean experience: by means of a philological critique, by means of a certain form of biologism, Nietzsche rediscovered the point at which man and God belong to one another, at which tile death of the second is synonymous with the disappearance of the first, and at which the promise of the superman signifies first and foremost the imminence of the death of man.
